METHOD OF REPLICATING VIRUSES IN SUSPENSION CULTURES OF DOG KIDNEY CELLS.

摘要

Animal cells are described which can be infected by viruses and which are adapted to growth in suspension in medium free of animal-derived components, such as serum-free medium. Processes for the replication of viruses in cell culture using these cells are furthermore described, as well as vaccines which contain the viruses or antigenic portions thereof obtainable by the process.
